Was driving my mazda cx-9 in afternoon traffic when the car in front of me applied their brakes to stop. I went to apply my brakes and the pedal was hard and nothing happened...the car would not stop. I then placed my other foot on the pedal in order to apply more pressure and still nothing. Heard a hissing noise and then realized this car was not going to stop. "scared the hell" out of me as I watched my car hit the car in front of me. Thank god I was not going fast or this could have been tragic.
Hi there ... We got rear ended last year ... I have had no luck getting our mazda repaired for the last couple of months ... Mazda has not called me back for repair
The tachometer of the car sticks in high revs (1500-2500),engine on, car in neutral, foot off the gas pedal, if the car is moving over 20-25MPH (either by free falling a hill or being pulled) the tachometer varies the RPM reading to match speed just as if the car would be in 'd' position. I think the ECU has a glitch of some sort that ignores the gas pedal and the shift position if the car is moving.
SUV would go off in the middle of the road or highway when traveling a high speed. Took it to dealer, they say that they found oil & water mix in the engine due to water pump failure, multiple symptoms would occur as due to this condition. This issue is very series, first you get no indiction of the problem, not sure why the water pump failure causes water to enter the motor and mix with oil, it must be a mazda design problem, which they seem to know about and never issued a recall to get all the car fixed.
There was first a whining sound from the transmission especially during coasting. It progressively got worse making a metallic clunking sound. Dealer says it is a bad transfer case (ptu) which is not covered by ssp92. Otherwise this repair would have been completed by mazda. Repair estimate is $1315.
